Embodiment 1
[0025] Embodiment 1: a kind of method of terpene resin hydrogenation comprises the steps:
[0026] 1) Resin synthesis: Adjust the cooling water temperature of the reactor to 20°C, add 30% cyclohexane and resin synthesis catalyst to the reactor, add turpentine and the remaining cyclohexane dropwise to the reactor within 60 minutes of reaction, and complete Carry out 2 hours of insulation after dropping, add water to the reactor after the insulation is completed, stir, stop stirring and let stand, drain the water in the lower part, and obtain the reaction solution of molecular sieve dehydration after dehydration with 5 micron molecular sieve; Among them, the resin Synthetic polymerization raw materials include the following raw materials in parts by weight: 600 parts of turpentine, 700 parts of cyclohexane, and 40 parts of catalyst; the resin synthesis catalyst includes the following components in parts by weight: 70 parts of aluminum trichloride, 10 parts of potassium sulfate, ...
Embodiment 2
[0029] Embodiment 2: a kind of method of terpene resin hydrogenation comprises the steps:
[0030]1) Resin synthesis: Adjust the cooling water temperature of the reactor to 10°C, add 35% cyclohexane and resin synthesis catalyst to the reactor, add turpentine and the remaining cyclohexane dropwise to the reactor within 60 minutes of reaction, After the dropwise addition, keep warm for 1 hour.
